2 Claims.

This invention relates to improvements in toilet venting devices and has particular reference to a device for removing .odors from the bowl of a toilet and conducting the same to a point below the trap of the toilet bowl.

A further object of the invention is to produce a device of this character which may be installed in the average toilet without detracting from its appearance.

A further object of the invention is to produce a device of this character which is automatic in its operation, and one which will not operate after the toilet has been flushed.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a side elevation of our device, showing portions thereof in cross section;

Fig. 2 is a fragmentary top plan view taken on the line 2--2 of Fig. 1;

Fig. 3 is a cross sectional view of the flushing tank taken on the line 3-3 of Fig. 2;

Fig. 4 is an end elevation of Fig. 3, showing the end wall removed.

Fig. 5 is an enlarged fragmentary detailed view, partly in cross section, of the switch actuating mechanism;

Fig. 6 is a cross sectional view taken on the line 6-6 of Fig. 5; and

Fig. 7 is a fragmentary detailed view of the seat hinge.

When the average toilet is used, it often occurs that objectional odors arise therefrom, and it is our purpose to remove these odors 4by drawing the same from the toilet while the toilet is in use and discharging these odors into the sewer pipe at a point below the trap in the toilet bowl.

In the accompanying drawings wherein for the purpose of illustra-tion is shown a preferred embodiment of our invention, the numeral 5 designates any standard form of toilet bowl having a water trap 6 and a drain 1. At 8 there is shown a iiushing tank connected in any desired manner with the bowl 5 and adapted to discharge water into the circumferential channel 9 and through openings II into the interior of the bowl. The structure thus far described is common to the average toilet.

Our invention consists in installing in the tank within a compartment I2 a motor I3, which drives a fan enclosed in the housing I4, the intake of which fan communicates with a pipe I6 having a gravity closed valve I1. This pipe I5 in turn communicates with a channel I8, preferably moulded in the tank and having its lower end communicating through a port Iii, with the discharge 2l connecting the tank to the bowl. 5 It is through this discharge 2i that the water from the tank enters into the bowl. A channel 22 connects with the discharge from the fan and to a channel 23 in the bowl, which in turn connects to the drain 1.

Consequently, when the motor I3 is running, air will be drawn from the interior of the bowl through the openings Il, through the circumferential channel 3, through the port I9, into the channel I8, past the valve I1, through the fan, and will be discharged through the channels 22 and 23 into the drain 1, thus removing any odors in the bowl and discharging' the same into the drain.

In order that the device may operate automatically, we provide a switching mechanism which is connected to the seat as follows:

The usual seat is shown at 24 and the cover therefor at 25, both being hinged to the pintle 21, which is attached to the top of the bowl 5. The 25 seat portion of the hinge is provided with a shoulder 28 which engages a shoulder 29 formed upon a pivoted lug 3l, this lug being mounted on the pintle 21. A lever 32 extends rearwardly through a slot 33 formed on the casing 34 and projects into a slider 36 movable ybetween guides 31. A spring 38 tends to normally maintain this slider in the position shown` in Figs. 5 and 6. A dog 39, pivoted in the slider, is normally maintained in the position of these iigures by a spring 4I so that its nose will be in alignment with a switch toggle button 42 mounted in the receptacle 43, preferably positioned in, the wall to which the tank is attached. Slidably positioned in the casing 34 is a rod 44 having its lower extremity 40 in alignment with the toggle 42 so that when the same is actuated from the full line position of Fig. 5 to the dotted line position of this gure, the toggle switch will be moved from its dotted line position to its full line position, the purpose of which will be later seen.

By referring to Fig. 3 it will be noted that the rod 44 is connected to a bell crank lever 46, which in turn is connected by a pull rod 41 to the lever 48, which is pivoted as at 49 and is actuated by 50 the handle 5I, commonly employed to ush the toilet. In order to simplify the drawings, the flushing mechanism has been eliminated.

The result of this construction is that when the parts are assembled in a toilet, the spring 38,

through its action on the end of the lever 32, will tend to maintain the toilet seat in a slightly elevated position, as shown in Fig. 1. The cover of the seat may be raised without aecting the action of the device. However, as soon as a person is seated upon the seat, the same will depress the shoulder 2S engaging the shoulder 29, causing the lug Iii to rotate and causing the lever 32 to swing upwardly, thus raising the slider 36 so that the nose of the dog 39 will engage the toggle ft2, moving the same to the dotted line position of Fig. 5, thus turning on the cur rent to the motor i3. Immediately, a current of a-ir will ow from the interior of the toilet bowl through the device, as previously described,

As soon as the person arises from the seat, the slider .'-lli will return to its normal position, but the nose of the dog will not engage the toggle and stop the flow of current through the motor. However, as soon as the person flushes the toilet, the rod lili will move downwardly, tripping the toggle and cutting off the current of the motor, and, at the same time, the flushing mechanism will be actuated to flush the toilet.

Should a person flush the toilet while still sitting on the seat, the same action will occur in that the motor will be stopped, but upon arising from the seat and when the slider moves downwardly, the nose of the dog will pass the now depressed toggle, which is permitted by the action of the spring di.

It will be apparent from this arrangement that during the time that a person is sea-ted upon the toilet and up until the time the toilet is ushed, there will be no odors escaping therefrom, and,

further, the device is automatic in its starting action as soon as the toilet is in use.

It is to be understood that the form of our invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described oui` invention, we claim:

l. In combination with a bowl and a tank, Ventilating means carried by said tank and connected through channels to said bowl, of a pivoted seat connected to said bowl, a slider actuated by said pivoted seat, said slider having a pivoted dog mounted therein, the nose of said dog being capable of engaging a switch lever when moved in one direction and avoiding said switch lever when moved in the opposite direction..

2, In combination with a bowl and a tank, Ventilating means carried by said tank and connected through channels to said bowl, of a pivoted seat connected to said bowl, a slider actuated by said pivoted seat, said slider having a pivoted dog mounted therein, the nose of said dog being capable or engaging a switch lever when moved in one direction and avoiding said switch lever when moved in the opposite direction, and independent means for actuating said switch lever with the flushing of the toilet.
